ListPopupWindow在输入后关闭

Question

我正在尝试在我的应用程序中使用提及类型弹出窗口，当弹出窗口出现时，用户滚动，然后继续键入弹出窗口解除。有没有办法让弹出窗口保持打开状态，直到我们调用dismiss？

这是我正在使用的代码。

    public class MainActivity extends AppCompatActivity
{

    private EditText editText;
    private ListPopupWindow listPopup;

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText = (EditText) findViewById(R.id.editText);

        String[] states = getResources().getStringArray(R.array.state_array);
        ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, states);

        listPopup = new ListPopupWindow(this);
        listPopup.setHeight(300);
        listPopup.setAnchorView(editText);
        listPopup.setAdapter(adapter);
        //listPopup.setModal(false);



        listPopup.setOnItemClickListener(new AdapterView.OnItemClickListener()
        {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id)
            {
                Toast.makeText(MainActivity.this, "Position " + String.valueOf(position) + " Clicked", Toast.LENGTH_SHORT).show();
            }
        });


        editText.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                if(!listPopup.isShowing())
                {
                    listPopup.setInputMethodMode(ListPopupWindow.INPUT_METHOD_NEEDED);
                    listPopup.show();
                    listPopup.getListView().setChoiceMode(AbsListView.CHOICE_MODE_SINGLE);
                    editText.requestFocus();
                }
            }
        });
    }

}
